René Has Two Last Names

"René, a new student from El Salvador, doesn't understand why his second last name is missing from his desk's name label. Adding it results in a name so long that his classmates make fun of it by comparing it to that of a dinosaur…When his teacher assigns the students the project of creating a family tree, René is determined to show his classmates and teacher why he has two last names and the importance of his dos apellidos." — School Library Journal
